USC safety Bubba Bolden, who had not played this season for previously undisclosed reasons, is no longer enrolled at the university, Bolden confirmed Monday.

Bolden, a sophomore, is to transfer to another school.

In a statement announcing his departure, Bolden said he faced lengthy disciplinary action for his role in an off-the-field incident that occurred in February in which he was cited for underage drinking at an off-campus party, violating the school’s code of conduct. Bolden added that he “participated in mutual trash-talking with fellow party-goers” and left with friends when “the vibe at the party turned unfriendly,” but no other details about his behavior were given.

The incident was reported nine days later to USC’s Office of Student Judicial Affairs, which began an investigation. The party hosts reported “feeling threatened by me that night,” Bolden said.

As a result, Bolden, 19, said he was handed a 28-month suspension that recently took effect. The suspension was not to be lifted until the party hosts, fellow students, had graduated, according to his statement. His mother, Breezy Bolden, said Monday that Bolden was suspended from attending classes, which is needed in order to play for the team and remain eligible.

A university spokesman could not be immediately reached for comment.

“My behavior at the party was not reflective of my character which my family, friends, teammates and many more admire, and for this I’m truly sorry,” Bolden said in his statement. “At this point, I’m 100% committed to ensuring that the lesson I’ve learned on and off the field will carry me to the next level.”

Bolden also thanked members of USC’s football program and alumni for their support.

Bolden said he never faced criminal charges nor was subject to an investigation by USC’s Title IX Office. A spokesman from the Los Angeles Police Department said Monday that they had no record of any complaints filed against Bolden. The school’s Chief Threat Assessment Officer, Patrick Prince, determined that he was not a threat, according to Bolden.

Prior to the season, Bolden was in line to start at safety opposite Marvell Tell, winning the job in preseason training camp.

But two days before the season opener against UNLV, Trojans coach Clay Helton announced that Bolden was out indefinitely due to an undisclosed matter. Over the following weeks, Bolden remained absent from practices and games. When asked about his potential return, Helton kept mum.

On Monday, an athletic department spokesman declined to comment on Bolden’s departure. Helton was not scheduled to speak with reporters until Tuesday evening.

Bolden arrived at USC as a four-star recruit from Bishop Gorman High in Las Vegas and made an impact on special teams in freshman season in 2017.

Along with Bolden’s departure, USC’s depth at safety has been thinned. Ykili Ross, a fourth-year junior, left the team a week before the season began in order to pursue a graduate transfer, and redshirt freshman Isaiah Pola-Mao suffered a season-ending shoulder injury in the Pac-12 opener at Stanford last month. The Trojans have only four available scholarship safeties, including freshman Chase Williams, who moved from cornerback to safety following Pola-Mao’s shoulder injury.
